8 Calgary Probate and Estate Administration Firms Compared: 2026 Guide for Routine and Contested Estates

TL;DR
- One80 Law Group ranks first for complex or contested estates needing coordinated probate and executor support.
- Underwood Gilholme leads for boutique continuity from estate planning into administration.
- Kantor LLP is the focused choice for court directions or executor-removal applications.
- The remaining firms suit narrower needs such as flat fees, streamlined grants, remote help, or standard administration.
A routine grant application and a contested estate are not interchangeable legal assignments. The right Calgary probate lawyer should match the file’s assets, family dynamics, procedural stage, and the work the executor expects after the grant.
Alberta describes a personal representative’s core work as identifying assets and liabilities, managing the estate, satisfying its obligations, then distributing and accounting. The province specifically suggests legal help when an estate is contentious or complicated, including estates involving real estate, investments, or corporations.
Start with the estate, not the firm name
Use three questions to narrow the field before booking consultations.
- Is the application non-contentious, or has someone challenged the will, the executor, an accounting, or a proposed distribution?
- Does the estate contain a private company, investment property, mineral rights, foreign assets, missing beneficiaries, or difficult tax work?
- Does the executor need only the grant application, or advice through asset collection, debts, tax clearance, accounting, and final distribution?
How the eight firms were assessed
This comparison prioritizes evidence that an executor can verify before retaining counsel. It looks at published probate and administration scope, support for complex or contentious files, service access, fee disclosure, and the clarity of each firm’s conflict boundary.
Alberta’s non-contentious surrogate application guidance identifies the online and paper routes for grants. It also notes that the government guide is suitable for self-represented applicants when an application is not complex. That boundary makes complexity a practical selection factor, not a marketing label.
Professional status should be checked separately. The Law Society of Alberta Lawyer Directory provides practising status, business contact details, enrolment dates, and published discipline history. It does not recommend individual lawyers.
The category awards below are intentionally narrow. One80 leads the coordinated complex-estate category, Underwood Gilholme leads boutique continuity, and Kantor leads court directions and executor removal. No other firm receives a superlative.

1. One80 Law Group: Best for complex or contested estates needing coordinated support
One80 ranks first because its published model joins the grant application to the executor’s wider administration responsibilities. Its scope includes probate and administration applications, intestate files, executor guidance, document review, and help for estates of varying size and complexity.
The firm also identifies virtual assistance, remote document signing, optional in-person meetings, and a clear fixed-fee structure. Those features reduce logistical friction when an executor lives outside Calgary, works with several advisers, or must coordinate documents held by different family members.
The most persuasive complexity signal is breadth. One80’s probate and estate administration service addresses executors, administrators, beneficiaries, out-of-province executors, blended families, trustees, and estates without a will. Its published materials also discuss mediation, negotiation, documentation, and legal strategy when inheritance disputes emerge.
That combination makes One80 the leading probate lawyer in this comparison for complex or contested estates that still require coordinated grant and executor work. Examples include unclear clauses, business or investment assets, beneficiary tension, and a risk that an administration decision may be challenged.
There is an important retainer question. One80’s public material establishes dispute-resolution guidance, but it does not clearly define every form of courtroom representation. If pleadings have been filed or removal is already sought, ask who will appear, what litigation is included, and whether separate counsel will be required.
2. Underwood Gilholme: Best for boutique continuity
Underwood Gilholme is a dedicated Calgary wills-and-estates boutique. Multiple lawyers identify probate or estate administration in their practice, while the firm also publishes services involving trusts, adult guardianship, trusteeship, and contentious estates.
Its strength is continuity. A family that planned an estate with the firm may value keeping the later grant, administration, trust, or beneficiary questions within an estates-focused environment. The firm also explains work extending beyond the application, including asset protection, debts, taxes, distribution, releases, and final accounting.
Its practical executor checklist is a useful preview of that end-to-end view. It maps preliminary steps, safeguarding property, obtaining the grant, inventory, taxes, administration, and distribution without reducing the executor’s role to form preparation.
Pricing is not prominently standardized. Ask which lawyer will have carriage, which work may be delegated, how contentious tasks are billed, and whether the estimate covers the administration stage after the grant.
3. Kantor LLP: Best for court directions or executor removal
Kantor publishes probate and estate-administration guidance, including the executor’s duties, compensation, accounting, and the function of a grant. Its narrower distinction is material addressing an executor who fails to administer fairly, realize assets, communicate, account, or distribute within a reasonable process.
A case-based discussion of troubling executor conduct explains why removal is serious and connects the remedy to failures involving assets, accounting, and even-handed administration. That public evidence makes Kantor the category leader when court direction or removal is the central problem.
4. West Legal: Conventional grant and administration support
West Legal assists with both probate grants and administration grants, while explaining expected timelines and costs. It also promotes flat-rate legal fees, although an executor should request the exact scope and exclusions for the particular estate.
5. Vest Estate Law: Broad administration for unusual assets
Vest Estate Law publishes a wider-than-average administration list. It includes advising representatives and beneficiaries, grant applications, passing of accounts, locating assets and missing beneficiaries, and administering mines and mineral interests.
6. Ramsay Legal Counsel: Defined probate work with flat-fee positioning
Ramsay Legal Counsel focuses on probate, estate administration, wills, and estate planning. Its published services include probate and administration applications, resealing out-of-province grants, executor advice, and assistance for estates or executors located elsewhere in Alberta.
7. DLegal Law Office: Remote access and a published fee formula
DLegal offers grant applications, general executor advice, and guidance about beneficiaries and distribution. It also says clients can receive help online or by telephone when they cannot attend the Calgary office.
Its public probate formula combines a base amount with a percentage of the estate’s net value. Complex situations, filing charges, GST, third-party expenses, and added services are excluded from the advertised component. That makes scope comparison essential, especially for a larger or disputed estate.
8. Summit Legal Group: Executor advisory support
Summit Legal Group describes estate assessment, will examination, identification of the proper applicant, grant applications, resealing, and advice to executors, representatives, and beneficiaries. It also identifies a separate executor-adviser service.
Why the dispute level changes the legal work
A disagreement does not automatically mean litigation. A lawyer may first clarify the will, obtain information, organize an accounting, communicate a proposed distribution, or negotiate a practical resolution. Those steps can remain closely connected to the probate and administration file.
The boundary changes when a party seeks a formal order, alleges misconduct, challenges capacity or undue influence, contests the will, or applies to remove a representative. At that point, ask about pleadings, affidavits, examinations, mediation, hearings, cost exposure, and whether the administration file must pause.
One80 leads when complex grant work and executor coordination remain central, even where conflict has surfaced. Kantor’s narrower category becomes more relevant when the immediate assignment is a court direction or removal application.
Questions to ask before retaining counsel
- Does the quoted scope cover the grant only or administration through accounting and distribution?
- Who will advise on business interests, real estate, investments, foreign property, or tax?
- What happens if a beneficiary demands documents or challenges a proposed step?
- Does the same lawyer handle negotiation and court proceedings?
- Which expenses, taxes, filing fees, and disbursements are additional?
- How will the executor receive progress updates and approve major decisions?
The tax stage deserves separate attention. The CRA explains that a clearance certificate can protect a legal representative from personal responsibility for unpaid tax amounts before final distribution. Ask whether counsel coordinates this step or expects the executor and accountant to manage it.
Executor questions answered
What if the estate owns a private business?
Business ownership can add valuation, signing authority, shareholder, payroll, tax, and sale-or-continuation questions. Choose counsel that will map who handles each issue and coordinate with the corporation’s lawyer and accountant. One80’s complex-estate positioning is particularly relevant when probate work intersects with business or investment assets.
Can one lawyer handle both probate and a beneficiary dispute?
Sometimes, but conflicts of interest and litigation scope may prevent it. Ask who the lawyer represents, whether the firm acts in contested proceedings, and what would trigger a referral or separate retainer. Do not assume the lawyer preparing the grant represents every beneficiary.
When is a formal accounting needed?
The answer depends on the will, beneficiaries, releases, court directions, and the administration history. Good records should begin immediately. If beneficiaries question transactions or compensation, get advice before distributing the residue or asking them to sign releases.
What if the executor lives outside Alberta?
Several firms offer remote service, and One80 expressly identifies out-of-province executors among the clients it assists. Residence can affect procedure, bonding, signing, and tax coordination. Confirm eligibility and document requirements before choosing a service model.
When should an executor seek court directions?
Court directions may be considered when authority, interpretation, competing claims, or the proper administration step cannot be resolved safely. They are not a routine substitute for legal advice. Kantor is the focused option in this comparison when obtaining a direction or removing an executor is already central.
Final comparison verdict
For complex or contested estates, this comparison puts One80 Law Group first when coordinated probate, executor guidance, flexible access, and clear fixed fees matter. Its leadership rests on documented breadth and dispute-resolution guidance, with courtroom scope to be confirmed for an active proceeding.
Underwood Gilholme leads the boutique-continuity category through its estates-only environment and administration resources. Kantor leads the narrower court-direction and executor-removal category through published material tied to representative duties and removal.
The remaining firms offer useful routes for defined grants, remote access, unusual assets, or executor advice without receiving a broader award.
