Ancestral property partition thorough document or Court which should b

My mothers ancestral property is divided among her two brothers 10 years back along with release deed signed by my mother. They transferred Ito there name with e katha, now they are ready to share some portion with us. Do they have right to make a gift deed? If not can we go for partition? As they are voluntarily giving it Should we make partition through court or just a partition deed doc prepared by lawyer. We contacted 2 lawyers one said go with just partition doc and another said do it via court. Could please clarify my doubt.. Thanks in advance
