I am not being asked to pay this inheritance tax. The seller is complaining that he has to pay it and wants me to pay a portion of it for him. No way Jose! I have been trying, through the lawyer, to get him to sign an agreement to sell at the requested pesos per liter square providing that there is a current clear title, he is who he says he is, that there are no other heirs or those who can lay claim to the property, and that the taxes are paid. It has been difficult and if he does not sign the agreement, I am out of the deal. Thanks for your input.
