Can I get a court-appointed lawyer for boating under the influence (bui) in Indiana?
Indiana's rule on court-appointed lawyers: Before public defense counsel is assigned, the court must find the defendant indigent; the judicial officer then assigns counsel. If the court finds the person is able to pay part of the cost of representation, it shall order a fee of $200 for a felony action or $100 for a misdemeanor action; other statutes allow courts to order reimbursement of reasonable attorney's fees and costs at any stage after determining ability to pay. Costs must be reasonable and not more than the cost of representation, and a court may not order an indigent defendant to pay based on possible future earnings. Ind. Code §§ 35-33-7-6(c), 33-40-3-6, 33-37-2-3; Davis v. State, 843 N.E.2d 65 (Ind. Ct. App. 2006)
How much does a lawyer for boating under the influence (bui) cost in Indiana?

What happens after an arrest for boating under the influence (bui) in Indiana?
How release before trial works in Indiana: Under Indiana Criminal Rule 2.6 (effective January 1, 2024), a court should release an arrestee who does not present a substantial risk of flight or danger to self or others without money bail or surety, subject to conditions the court sets. This does not apply to arrestees charged with murder or treason, on pretrial release for an unrelated incident, or on probation, parole or other community supervision. In assessing risk, the court should use the results of an evidence-based risk assessment approved by the Office of Judicial Administration plus other relevant information, but need not run an assessment first if that would delay release. If money bail is required, the court sets the amount and decides whether a surety bond and/or cash deposit may satisfy it, and may accept a partial cash deposit. Cash bail deposits may be retained to pay fines, costs, fees, restitution and publicly paid costs of representation. Ind. Crim. Rule 2.6(A)-(C); Ind. Code § 35-33-8-3.2(a) What happens after an arrest.
