Health insurer claim after 5 years? Get clear advice!

Questioner

Can a health insurer, after more than 5 years (claim resulting from (according to them unjustified) payment to my partner), still recover the money from us? They indicate that they sent a letter, we have nothing left in the house from 2013. We have not received any registered letters or reminders. In our opinion, they have not maintained active contact about the claim during all this time We also cannot find anything on our section with the insurer. They are now starting to nag after we filed a claim and I read my partner's letter about a payment arrears and I called them Now they want the claim, but I have no idea if the 5 year rule applies. They say no and I don't know kind regards, theo van eck
