There is very limited scope to change any clause in a MOA (now called a
Separation Agreement) - the clauses that can only usually be amended are
those relating to periodical payments (aliment, child maintaince)
If you didnt receive sufficient and proper
legal advice at the time of signing the SA, then
you may have grounds to have the SA amended, but if you did, then it is
very unlikely that you will have sufficient cause to change any clause
within the SA, esp if you are now seeking a change to the SA due to a
change in your own circumstances.
I appreciate this isnt the
answer you were hoping for
