Can I add someone to my title without going through a lawyer

First
Why are you adding someone
Are you sure you want to give partial ownership to another person

Do you have any type of written agreement if your relationship goes bad as to what happens to the house.

Do you have a lien ( loan) on the house, and if yes, have you gotten permission from the lender to add someone.

Those answers will help us in what process would be best

At the top of the Real Estate Law forum there is a sticky post that explains how to do it. You can read it at https://www.askmehelpdesk.com/real-estate-law/how-add-someone-your-deed-91136.html
