You'll need the advice of your trustee before you do anything.
This because if you saved up this money during your bankruptcy,
then it may still be fair game for your creditors.
And of course if you have concealed that money from your trustee so far,
then you may have a bigger problem.
Further, you don't get to call it a gift and just expect it to be so.
Even if you call it a gift, you will need to show your Trustee
that it is not in fact an unsecured loan,
or a capital investment in the new business.
This is almost impossible... if only because the first question you will face
is something like...
"How did you afford to save twenty grand over two years,
out of an income below the threshold amount,
why was it not being applied to your debts, and why should it not be now?"
