Can I Freeze or Stop an Estate From Being Distributed While I Dispute the Executor in Alberta?

This answer covers the law of Alberta.

It can be possible, but the tools depend on timing. Before a grant is issued, anyone may apply to the Court of King's Bench to restrain dealing with the deceased's property, and a caveat blocks grant proceedings for 3 months unless the Court orders otherwise. A caveat is a way to pause things. It does not decide who is right.

After a grant issues, only the executor named in it may act, and beneficiaries cannot replace that person by agreement among themselves. On application, the Court can order an executor to perform a duty, impose conditions such as security, remove the executor or revoke the grant. Removal is an option, not the automatic result of a failure. Distribution is properly delayed until claimant-notice steps are done, but the executor must still distribute as soon as practicable.

Start by trying to resolve the concern through discussion; if that fails, you or your lawyer may apply to the Court. The Public Trustee does not get involved in private disputes about how an estate is being administered. Gather the will and any notices you received. Because the right step depends on whether a grant has issued, speak with a lawyer promptly.
