Although the law establishes an order of succession when there is no will, making a will is fundamental for several reasons. The will allows you to express your will on aspects that the law does not contemplate: you can designate specific heirs respecting the legitimate rights but distributing unequally the third of improvement among your children according to their needs, make bequests of specific assets to specific persons without integrating them into the general estate, appoint guardians for your minor children choosing who will take care of them if you are absent, establish usufructs that protect your spouse economically, make provisions on family businesses ensuring their continuity, and include clauses that prevent future conflicts. In addition, the will greatly expedites the processing of the inheritance avoiding more complex procedures for the declaration of heirs. It is a minimal investment (notarial wills cost between 40-80 euros) that can avoid very significant patrimonial and family problems.
