Four-fermion final state processes result in distinctive experimental topologies at LEP-2 energies, and have cross-sections typically in the picobarn range. They are interesting to measure both to verify the SM prediction as such, and because they can constitute significant background to new particle searches. In this talk we review preliminary results obtained in DELPHI for the processes ZZ, Zgamma*, Wenu and Zee.
