MGS: cancelling, claims and complaints

MGS SEGUROS Y REASEGUROS S.A. has its head office in Zaragoza, Spain. The Spanish insurance supervisor DGSFP lists it under code C0794. This page explains where your cancellation goes, the notice period under Spanish law, how to report a claim and whom to contact with a complaint.

How to cancel with MGS

Send the cancellation to the address on your policy. If none is given, the head office is right:

MGS SEGUROS Y REASEGUROS S.A.
Calle Don Jaime I, 32
50001 Zaragoza
Spain

Spanish policies usually renew for one year at a time. To stop the renewal you must tell the insurer in writing at least one month before the current period ends; the insurer needs two months (article 22 of the Spanish Insurance Contract Act, Ley 50/1980).

Give your policy number, your name and the date, and ask for confirmation of receipt.

Reporting a claim to MGS

  1. Spanish law requires you to report the loss within seven days of learning about it, unless the policy allows longer (article 16, Ley 50/1980).
  2. You must do what you can to limit the consequences (article 17, Ley 50/1980).
  3. Collect photos, receipts and names of witnesses; for theft you also need a police report (denuncia).
  4. Keep your policy number at hand.

Phone and website from the register; your policy takes precedence.

Complaints about MGS

MGS does not appear in the rankings of the DGSFP complaints report for 2024. The report only names the 25 insurers with the most complaints or the highest rate in each table, not a complete list.

Where to complain

In Spain every insurer must run its own complaints service (Servicio de Atención al Cliente). If it does not answer or the answer does not satisfy you, you can turn to the complaints service of the supervisor DGSFP (Orden ECC/2502/2012).
