Hadronic (Pi+Pi-) atom is studied in the relativistic perturbative approach
based on the Bethe-Salpeter equation. The general expression for the atom
lifetime is derived. Lowest-order corrections to the relativistic Deser-type
formula for the atom lifetime are evaluated within the Chiral Perturbation
Theory.
