Legal Question in Real Estate Law in California

You either hold title as joint tenants or as tenants in common. You can't be both. I suggest you iron out that detail first. You cannot have a co-owner evicted from a house, and if you are a cosigned on the loan, you can make payments any time you want.

How??

With difficulty, time, and a lot of legal fees to be incurred in a lawsuit over ownership interests and financial accounting, if you can't reach a voluntary settlement between yourselves.

If serious about hiring counsel to help either negotiate a settlement or litigate this before it is too late, feel free to contact me. I’ll be happy to help fight and get the best outcome possible, using whatever evidence and sympathies there may be. I’ve been doing these cases for many years.
