I own a co-op and I would like to add him to the deed for the co-op. Do I need a lawyer or is there a form we can complete and submit to the courts.

You should discuss this with the co-op board. First you will need approval to add and possibly a new deed as a codicil is typically not accepted for a deed. Rules of this nature are state based and they can all differ. I would not attempt to self add by just a form, it could easily be denied. An attorney could give you guidance.

Thank you, we will contact the board to make sure.

Also, note that if you have a mortgage on the property, you will not be able to change it, without their permission, since they hold a lien on the deed.

Thank you, we have no mortgage on the co-op. Will there be tax implications if my son is added to the deed?
