abstract="We show that if global lepton number symmetry is spontaneously broken in a postinflation epoch, then it can lead to the formation of cosmological domain walls. This happens in the well-known {\textquoteleft}{\textquoteleft}Majoron paradigm{\textquoteright}{\textquoteright} for neutrino mass generation. We propose some realistic examples that allow spontaneous lepton number breaking to be safe from such domain walls.",
