Prudential pension should i keep it or get a new one

[cutecockerpoo12]

Hello i have a prudential pension that is worth 4ok.
I am now mortgage free and want to start paying those premiums into my pension.
I am 54 and self employed. Should I just get a new pension. Or keep the prudential one.

I know when I was 50 they kept contacting me but I just ignored it.
as well as what are the charges ?
can I contribute ?
will my wife get it if I die ?
anything else please ?

I’m just putting an email together to the prudential.
what do I need to know ?
before I start contributing.
the crucial questions are
will my wife get my full pension if I die
any hidden costs ?
please has anyone got any other advice before I send this email.
so grateful.
