Yes to baptisms and some aspects of funerals. But NEVER marriages. 

In most Western democracies, a state licence is required for anyone officiating at a wedding, including all Christian ministers. Bishops, priests, and deacons acquire those licences as a matter of course so that the Catholic wedding rituals are recognized by the state as well as the Church. Now it is true that Granny Smith could acquire a license to perform secular marriages, but she may not officiate at a Catholic sacramental marriage. 

Do we disagree?
