Swiss Civil Code

¹ A mort­gage right may be cre­ated on two or more prop­er­ties for a single debt provided the prop­er­ties are all owned by the same per­son or by debt­ors who are jointly and sev­er­ally li­able.

² In all oth­er cases where more than one prop­erty is made sub­ject to a mort­gage as se­cur­ity for a single debt, each of the prop­er­ties shall be en­cumbered for a spe­cified por­tion of the total debt.

³ Un­less oth­er­wise agreed, the total amount se­cured by the mort­gage is di­vided in pro­por­tion to the val­ues of the prop­er­ties.
