Heather MillsPaul McCartney and Heather Mills‘ legal tussles may not be over even when the High Court judge overseeing their case makes his decision on their divorce settlement early next month.

According to the News of the World, Paul is keen to appoint daughter Stella onto the board of trustees taking care of Paul and Heather’s four year old daughter’s financial assets - but Heather has made it clear she’s oppposed to the idea.

Heather and Stella are said to have fought frequently during the former model’s four year marriage to Paul and their relationship was strained even further when Heather claimed Paul abused Stella’s mum, Linda McCartney.

A source told the newspaper that Paul wants to make the appointment to have someone represent his views should anything happen to him before Beatrice’s 18th birthday but Heather thinks it’ll only cause trouble: “Heather wants none of it, and has told Paul in no uncertain terms that she will fight any role Stella has in Bea’s life.”

Last week, Paul and Heather failed to reach a settlement after a six day hearing at the Royal Courts of Justice in London. It is now up to Judge Hugh Bennett to draw up details of a financial settlement. Heather is expected to get a lump sum in addition to a yearly child support payment of around £2.5million until Beatrice turns 18.
