What document is primarily needed to validate a person's estate after their death?

The grant of probate is a crucial document needed to validate a person's estate after their death. This legal process ensures that the deceased's wishes, as outlined in their last will and testament, are carried out effectively. When a person dies, their assets and liabilities must be managed according to their will. The grant of probate is issued by the relevant court and confirms the authority of the executor to administer the estate. It serves as proof that the will has been legally recognized and accepted, allowing the executor to distribute the assets to the rightful beneficiaries.

The last will and testament, while important, primarily expresses the deceased's wishes regarding asset distribution and does not itself carry legal weight without being probated. A living will is related to healthcare decisions and does not address estate validation. A marriage certificate, although important for confirming marital status, is not used for the probate process or validating an estate. Therefore, the grant of probate is the essential document for ensuring that an estate is properly managed after someone's death.
