Tell your brother that neither you, nor the judge can change the terms of your father's Will. Explain that your brother's unwillingness to sign his receipt simply makes the process drag out and costs money.
If he continues to refuse to sign the receipt, then present the canceled $1000 check to the judge and explain the situation. The judge can then decide what to do.
Your brother cannot make anything happen simply because he is unhappy with your father's Will.
To your Success,
Gale Allison, Principal Attorney
