Step One: Talk about it. Experts agree communication is essential in maintaining a good relationship - and this also applies to money matters. Couples who are open with each other about money will find it less a source of conflict.
'Every relationship is different, every financial situation is different,' says ipac's Pam Bradley.
'The sooner you get talking about money, the easier it is.
'It is like everything else: the first time you ride a bike and you fall off and it hurts, and before you know it your riding the Tour de France.'
Step Two: Act like a celebrity - and consider a pre-nuptial agreement. It's well worth considering.
'It doesn't hurt to have a prenup and they are great because they get you talking about your finances,' says Bradley.
The best time to write a prenup agreement is when you have just become engaged or taken the equivalent step of commitment.
