Dear Kevin,

Your sister-in-law could contest the will in the event that no other assets had been left to her, and providing your mother-in-law had left all her estate to your wife, as in Spain the rights of the legitimate heirs are respected, as opposed to the UK law, where there is free disposition of the assets. Therefore, I would need to have more details on the case to advice further.

We can certainly assist in the matter, so please feel free to send us the relevant information by e-mail through our website´s contact form.

Best Regards,
