Legal Question in Real Estate Law in Maryland

Generally all owners must agree before property can be sold unless the court takes charge and gives someone else authority to sell.

If co-owners cannot agree, any of the owners can go to court and force a sale through a type of case called a sale in lieu of partition action. Basically the court will appoint a third party (trustee) to take over the house, sell it under terms reasonable to the trustee and disburse the proceeds among the various co-owners.

As with most litigation related claims, it is advisable to seek legal counsel. Naturally litigation costs time and money and may not be the best route in every case. While I hope this general information helps it doesn't create an attorney/client relationship or take the place of getting private advice specific to your situation.
