Do I need to remove a deceased co owners name from deed?

Yes, it’s usually a good idea. Removing the name helps avoid title issues when you refinance or sell. The process is often simple, usually involving a death certificate and a recorded document with your county.

Contact a Probate or Real Estate Attorney to see if they can help, and what documentation they may need.

I would strongly suggest contacting a local real estate attorney. Most can answer this question at no charge.
