In the case where A and B are married and B dies, what is the proper procedure to transfer title?

When handling the transfer of title after the death of one spouse, the proper procedure typically involves filing a death certificate. This document serves as official legal proof of the spouse's death, which is essential for any subsequent actions regarding the transfer of property title. The death certificate provides necessary information to the title company and can be required by various governmental organizations involved in the probate process or property transfer.

The other procedures, while they may be relevant in the wider context of estate management or property transfer, are not specifically aimed at notifying the necessary entities of the death itself. For example, filing a probate claim may be necessary later to settle the estate, and transferring property through a will would occur after the probate process is initiated. Similarly, notifying the court might be part of the process, but it usually follows the establishment of the death through the filing of the death certificate. In essence, the death certificate is the foundational document needed to initiate any subsequent legal or administrative actions regarding the deceased spouse’s property.
