Final salary pension cetv or actuary?

My husband has a final salary pension from a major high st bank in deferrment-CETV of 248K
Total GMP value £25400 & total value of benfit for leavers after 5/4/97 of £35350


I have a Final salary pension in deferrment CETV of £39600 with a GMP of £26 pw. We estimate equity in the FMH when sold to be about £205K. He intends to allow me to keep the equity & some other assets worth about £20k in total. You can see from these figures that there is a fairly even split if based on CETV values. I am unsure whether to get an actuarial report to assist with accurate offsetting.Will it be more expensive than it's worth in my case?

I am now earning a small salary of £14k pa & my husband is self emp but earns significantly more than me. I have 2 of our children living with me in FMH & he pays private maintenance for them & me which he wants to reduce when I downsize. I am concerned after the children leave that I wil'll not get maintenance & that on retirement my pension will be about £5k pa & not enough to live on. I may seek a pension share but not sure if I am likely to succeed. Was married 26 years & looked after family not working for 15 years.
