Article 934

If the testator should bequeath or devise something pledged or mortgaged to secure a recoverable debt before the execution of the will, the estate is obliged to pay the debt, unless the contrary intention appears.

The same rule applies when the thing is pledged or mortgaged after the execution of the will.

Any other charge, perpetual or temporary, with which the thing bequeathed is burdened, passes with it to the legatee or devisee. (867a)
