Agricultural land despute

My grandfather was two brother. My grandfather had four sons, and grandfather's brother have no son. Earlier property was devided into 4 equal parts except 4 acres of land. this 4 acre of land was given to grand fathers's brother for their livelihood and promised to be equally divided into all after he passed away. grandfathers brother was in my fathers side thatswhy we were enjoy the property. earlier we were not reluctant to share property to brothers, but my grandfathers brother remain alive for more than 30 years of division. in mean time there is human nature greediness came in my mind, i had made a will from registered advocate, in which it was written that after death of my grand fathers' brother death whole of 4 acres will be enjoyed by me only..... as i had served that old fellow for more than 30 years of critical phase. I dont think i had done wrong. as and when my uncles came to know about my will, they went to court and objected my possession in the land which was registered in their name from 1950s. Magistrate given judgement in their favour. I applied in judge court and won the case on the basis of being ancestral property. Now matter in high court, what should i do to continue enjoying my share. what should I avoid?
