Redundancy payment.

When I signed my trust deed I was due to go on maternity leave. My trust deed was granted and I was to pay a smaller amount while on maternity leave and then it was going to be increased when I went back to work. Unfortunately I was made redundant so I have only been able to make the smaller payment to my trust deed. I am now finally receiving redundancy payment in instalments from my old employer so I am going to contact my trust deed company to increase my payments so my trust deed still finishes in march or april next year however I think I will still be receiving redundancy instalments after this time.
My question is will my trustee continue to take payment from me if I am still receiving redundancy payments even when the trust deed has ended.

I hope this all makes sense
