Fortunately for the OP, there is a substantial enough community of Spanish Brits, and asking them — even online — can be enlightening;whether it’s about finding a lawyer already well-versed in Spanish and British citizenship and residency matters (including that related to taxes, estates/probate and/or family law matters) or to get a sense from others who have gone through the situation without using a lawyer and how that went.

This doesn’t mean to take everything or most everything said online in a travel forum,as gospel, but it also doesn’t mean that there is no useful citizenship information to be sourced on FT too. There is at times.
