1. The costs become payable on the making of decree
absolute, not before.
2. If the amount is not
agreed, your solicitor prepares a bill in a specified form and serves it on
the other party with what is called a notice of commencement of
assessment.
3. If the other side file no objections, your
solicitor obtains a default costs certificate from the court. This
specifies the amount to be paid. You now have a money judgment which can
be enforced the same way as a debt.
4. If there are
objections to the bill, either you thrash out a deal or the court
will list a hearing for the judge to decide on the amount. Once the judge
has decided, that also is a money judgment and is enforceable.
