Yes it does. A rule of forced heirship  is any rule of law in a jurisdiction other than Seychelles which in order to protect or give effect to the rights of any person or class of persons to inherit, succeed or to share in the settlor’s property on the settlor’s death, removes the settlor’s right to deal with the property as he wishes.
Section 10(2) of the Act says: “neither the trust nor the transfer or disposition shall be invalidated by any foreign rule of forced heirship, or by reason of the fact that the concept of trust is unknown to or not admitted by the law of a jurisdiction other than Seychelles;”
