My parents passed away 6 years ago at which time I was named executor of their trust/ will. My brother and I were sole eirs and all asetts were to be split except for the Home. The property was to be sold and money split or one could buy the others half at half the appraised value. We opted for the latter with my brother to pay me for my half. He has made no effort to pay and I need to know my legal rights to collect this debt.
