There are early repayment clauses with some loans so I guess it would be
wise to find out if any of those apply to part payment and make sure they
are covered.
You will be paying interest on the loan you take
out for your "share" so it would be iniquitous for you to pay interest on
the remaining debt i.e. his "share".
What you should think about
is how the financial split will work on divorce .. is this debt something
that can be offset against other assets? Have you a property,
pensions etc? How long is the marriage? Are
there children to consider? What are you respective ages and incomes?
I would be sure, whatever you do that you have a VERY clear paper
trail. There is a danger that the loan you take - because it is post
separation - could lead to
that debt not being counted as marital unless you can be very clear about
how it arose.
