My mom needs to get her land transferred into her name.

Please accept my condolences on the loss of your father.   As for your question, if your mother has a court order or divorce decree that says the land was to have been transferred to her, but the land never was transferred to her, then she is effectively a creditor of your father's estate. You (or someone else) will likely need to get appointed as the Executor or Administrator of your father's estate, get the estate administration started, and, assuming that the land does not need to be liquidated in order to pay creditors that have higher-priority claims than your mother's claim (she would be an unsecured creditor with a lower priority than certain other creditors), eventually turn the property over to your mother in satisfaction of her creditor claim. The rest of the estate, if there is any, can then be distributed to the beneficiaries or heirs.   Get the help of an experienced probate attorney if you want to take on the estate administration. It's not a good do-it-yourself project. Best wishes to you and your family.
