I'm afraid not, your partner's claim is theirs only, it does not apply to you.
If you apply for New Style ESA and receive an LCW award then you will receive payments for 365 days, if you are given LCWRA (Support Group) then your ESA will remain in payment as long as you stay in the group and you will still have the 365 days if you are subsequently moved to LCW.
