Couple: one LISA, one Help to Buy ISA

Hello all

Apologies if this has already been asked - I can't find it if so.

I have a Help to Buy ISA, which was preferential for me as my pension is terrible, so I'm thinking of opening a LISA in the next year or so exclusively for that purpose.

My wife, however, has a good pension. She could open either a LISA or a Help to Buy ISA. We're not looking to buy our first home for a few years yet (we're lucky sorts renting off a family member indefinitely at the moment).

I presume a LISA and a Help to Buy can be combined, despite being a mixed package, like two first time buyers can with two LISAs or two HTB ISAs? I can't find this definitively written down anywhere and while it seems like common sense that they can, to assume is to... etc!

Many thanks for any insight!
