SIR Michael Caine's son-in-law has been targetted in lawsuit by a disgruntled former pal who has accused the businessman of failing to pay him a cut of a big-money property deal.
Michael Hall, the husband of Caine's daughter Natasha, is being sued by Edward Kay, an ex business associate, who alleges he is owed money for introducing Hall to rich investors.
The investors helped finance a luxury gated-community which Hall's company, Obsidian, built in Uruguay.
Kay claims the pair's friendship soured in 2006, but Hall promised he would still be paid a share of the profits for bringing in the investors - agreeing a pay-off of $613,500 (£409,000).
But Kay insists Hall has only paid him $396,000 (£264,000) - and is suing for the remaining amount of $280,500 (£187,000).
Hall married Natasha, Caine's only child with wife Shakira, in 2007.
