Spouse-Survivor Status in Spain and Germany: the Pragmatic Solution of § 1371 BGB (2026 Analysis)

Introduction

Within continental European law, Spain and Germany share deep roots, yet the German *Bürgerliches Gesetzbuch* (BGB) offers a remarkably pragmatic contrast on how marital property is liquidated and how it ties into succession — a connection that in ordinary Spanish civil law tends to be rigid and litigation-prone.

1. *Zugewinngemeinschaft*: community of accrued gains

Germany's default marital regime is not community of property but the community of accrued gains (*Zugewinngemeinschaft*). During the marriage it works, for practical purposes, as separation of property: each spouse manages their own estate and is liable for their own debts. The true nature of the regime emerges at dissolution, when the gains each spouse made during the marriage are equalised.

In Spain, by contrast, the *sociedad de gananciales* requires an inventory, payment of common debts and division of the remainder into two exact halves. When triggered by death, this process is heavy and conflictual, especially where children of previous marriages or other forced heirs are involved.

2. The pragmatic German solution: *mortis causa* equalisation

To avoid those conflicts, German law devised an elegant fix. Where the marriage ends by death of one spouse, the equalisation claim is satisfied by raising the surviving spouse's intestate share by one quarter (§ 1371 BGB) — regardless of whether the survivor actually made smaller gains.

The survivor's base intestate share (one quarter with descendants) thus rises by another quarter, giving the widow(er) half of the estate in full ownership in a single legal act (§ 1931 BGB).

3. Comparative analysis

In Spain, family law (liquidation of *gananciales*) and succession law (widow's usufruct) operate in separate boxes that must be executed independently. In Germany, both spheres dovetail: liquidation is absorbed into succession, drastically cutting paperwork, asset-splitting and friction with forced heirs.

For Spanish-German couples on the Costa Blanca, the choice of applicable succession law under Article 22 of EU Regulation 650/2012 matters enormously: choosing German law often simplifies the estate, while sticking to Spanish law triggers heavier forced heirship and widow's usufruct.
