Change in Property Ownership with Complication of DV Case

My brother (Hindu) made a full down payment for a property with 50% contribution from our father. (Bank records of Money transfer available). Unfortunately, under pressure from his wife, he got the property registered under the joint ownership of him and his wife. 3 months ago he moved to a different city to join a better job. Almost immediately his wife filed a false Domestic Violence case against him. In addition to asking for maintenance in her original petition, she had also asked for a restraint against change in the house ownership.. The DV petition has been responded to in court, after which she did not turn up in the next hearing. On inquiring with her lawyer he has said that she would now like a mutual divorce. With the case still pending, can we get the house ownership changed at this stage or any later stage ? At what stage will it be viable to resume residence in the house by my brother and/or parents in the property ?
