Question juridique clé
Whether the conditions for adult adoption under Art. 266 para. 1 no. 3 CC were met, in particular whether other just causes existed.
Solution extraite
The relationship between Y. and X. was sufficiently close and filial in nature to constitute other just causes for adult adoption.
Motifs extraits
The court relied on the long shared household, the explicit adoption letter, witness testimony, testamentary and administrative acts showing mutual support, trust, and a relationship comparable to natural filiation. Purely financial motives were not established.
