Single people could soon have the same rights to adopt children as married couples, under the most dramatic shake-up to Victoria's adoption laws in more than 30 years.

Decades after the state's Adoption Act was introduced, the Andrews Government is preparing to revamp the legislation after conceding it no longer reflects "the modern family".

Changes to Victoria's adoption laws could give single people the same rights as married couples.

The proposed re-write is based on a Law Reform Commission report tabled in Parliament on Wednesday, which recommends widening eligibility requirements, giving children more access to information and support, and improving the way a person's identity is reflected in their birth certificate.

"At the time of its introduction, the Adoption Act represented a significant change in Victorian adoption policy, as it brought in open adoption," says the report, which was commissioned by the government in 2015.
