Regrettably according to statistics one in three marriages currently end up in divorce. It is therefore perhaps sensible that one should consider the possibility before it actually happens and therefore consider a pre-nuptial agreement.
As such if you are contemplating marriage a pre-nuptial agreement is something you perhaps ought to consider. If however you are already married there is the possibility of preparing what is termed as Post Nuptial Agreement. This will enable parties to reassure themselves and be aware of the financial consequences of a divorce.
For both a Pre Nuptial and Post Nuptial Agreement to be enforceable by law bothparties should seek independent legal advice.
