Seguro decenal

Compulsory insurance covering a residential building's structural damage for ten years: foundations, beams, floor slabs, load-bearing walls. The developer takes it out before selling, and without it the notary and the Registry will not accept the new-build declaration: it is a filter protecting buyers. The important exception is the self-developer: whoever builds a single-family home for their own use is not obliged to take it out. But if that house is sold before ten years have passed since completion, the seller must contract the insurance unless the buyer expressly releases them knowing the situation. Anyone buying a villa under ten years old built by its owner should examine this point closely: releasing means waiving the structural guarantee, and banks may be reluctant to finance the purchase.
