Transfer of mineral and royalty ownership, tax question

Sorry for your brother’s condition.

This could be accomplished a couple of different ways. A simple land trust could be created, then the properties would be deeded into the trust. Upon your brother’s death the trust would transfer property to you. Oklahoma has no estate taxes. Another option may be to use Transfer on Death Deeds for the properties. Upon his death you as beneficiary would file affidavits to claim the properties.

That would be a problem. Perhaps a better solution is to name you as his power of attorney so that you can help him manage his income while alive. That way he is still liable for his own taxes for that income.
