WI SB1043

Requires legislators to file a sworn residency certification and two proof-of-residence documents (such as driver's license, property tax bill, or lease) with the Legislative Reference Bureau and chief clerk at the start of each biennial session and annually thereafter

Mandates legislators notify the LRB and chief clerk within 10 days of any change in residence, with updated sworn statement and documentation

Creates an expedited quo warranto process: when the LRB or chief clerk has credible evidence a legislator doesn't reside in their district, the attorney general must determine probable cause within 30 days and immediately commence action to declare the office vacant if warranted

Allows any district elector to file a quo warranto action if the attorney general fails to act after receiving credible evidence of non-residency

Amends the legal definition of elector residency to specify "principal or primary home or place of abode" and changes intent language from "intends to return" to "has the present intent to return"
