Maddy summarySB 586 amends Michigan's guardianship law to require courts to document on the record why moving a person under guardianship (a "ward") from their current residence is necessary. It also mandates that guardians consult with the ward before making major decisions affecting them, such as changes to their living situation. The bill specifically updates sections 5306 and 5314 of Michigan's Estates and Protected Individuals Code to clarify these requirements. These changes directly affect guardians, wards under guardianship, and courts overseeing guardianship cases.

Probate: guardians and conservators; licensing of guardians; provide for. Amends title & secs. 5106, 5313 & 5409 of 1998 PA 386 (MCL 700.5106 et seq.) & adds secs. 5106a & 5106b.

Maddy summaryThis bill establishes a mandatory licensing system for professional guardians and conservators in Michigan, requiring them to be licensed by the state department before they can be appointed by a court. To obtain a license, applicants must meet specific criteria including being at least 21 years old, passing a background check, having no history of fraud or abuse, and successfully completing a national certification exam. The legislation also mandates that employees of licensed guardians and conservators must be licensed to make critical decisions regarding the care of the individuals they serve. Additionally, the bill requires professional guardians to file a bond, maintain a regular visitation schedule, and disclose any outside compensation received for their services. These changes aim to standardize qualifications and oversight for individuals managing the affairs of those under legal incapacity.

Businesses: limited liability companies; power of limited liability companies to spend in elections or ballot issues; revoke. Amends secs. 105, 210, 211 & 1008 of 1993 PA 23 (MCL 450.4105 et seq.) & adds sec. 210a. TIE BAR WITH: SB 1085'26, SB 1086'26

Maddy summaryThis bill prohibits limited liability companies in Michigan from spending money to support or oppose candidates, political parties, or ballot measures. It applies to both companies formed in the state and those from other states doing business here, with exceptions for existing contracts and bona fide news reporting. If a company violates this rule, the state can invalidate the spending, order the company to return the funds, or dissolve the company. The legislation also clarifies that a company's lack of legal power to make political donations does not automatically make all its other business actions invalid. This measure is tied to two other bills and will only take effect if all three are passed into law.

By updating existing statutes and inserting new provisions, the legislation aims to remove previous ambiguities about how nonprofits can manage their assets and support affiliated businesses. This change directly affects nonprofit corporations across the state by formalizing their ability to engage in complex financial arrangements necessary for their operations.

Businesses: other; power of entities to spend in elections or ballot issues; revoke. Amends the state constitution by adding sec. 55 to art. IV.

Maddy summaryThis proposed constitutional amendment would prohibit businesses formed in Michigan and foreign companies authorized to do business here from spending money to support or oppose candidates, political parties, or ballot measures. The rule applies to corporations, nonprofits, and limited liability companies, but it allows exceptions for existing financial contracts and independent news reporting or editorials. If a business violates these restrictions, the state attorney general could sue to invalidate the spending, force the company to return the funds, or dissolve the entity. The measure would also allow the state to revoke the operating authority of any foreign company that breaks the spending ban.
