Sweden

Surrogacy is not clearly regulated in Swedish law.[20] The legal procedure most equivalent to it is making an adoption of the child from the surrogate mother. However, the surrogate mother thereby has the right to keep the child if she changes her mind until the adoption. Yet, the biological father may claim right to the child.

It is illegal for Swedish fertility clinics to make surrogate arrangements.
