With increasing trends in divorce, separation and multi-partner fertility, more families have become subject to child support policies. This paper explores child support receipt in 21 European countries using 2017–2018 European Union Statistics on Income and Living Conditions data. We investigated: (1) cross-country differences in the prevalence and amount of child support received and (2) the determinants of child support receipt among lone mothers across countries. We found that the proportion of lone-mother families receiving child support ranged from 16 per cent in Luxembourg to 75 per cent in the Czech Republic, with large variations in the amount of child support received. Our results suggested that the socioeconomic characteristics of lone mothers, including marital status, education, employment status, number of children and income, were associated with the likelihood of receiving child support in most countries but these associations varied significantly across countries.
