You cannot apply for the five-guarantee household if you have children, unless the children cannot support them.

1. According to the law: the objects supported by the five guarantees (hereinafter referred to as the objects of the five guarantees) refer to the elderly, disabled people and minors among the villagers who meet the following conditions; (1) No legal support obligations person, or although there is a legal support obligor, the support obligor has no ability to provide support; (2) Inability to work; (3) No source of livelihood.

2. Article 6 of the "Regulations on Rural Five Guarantees Support Work Yet to Be Dealt with" Villagers who are elderly, disabled or under 16 years of age have no ability to work, no source of livelihood, and no legal obligation to support, support or support. If a person, or his legal obligor for support, support, or support is incapable of support, support, or support, he shall enjoy the five-guarantee treatment in rural areas. Article 7 To enjoy the five-guarantee treatment in rural areas, the villager himself shall apply to the village committee; if he is unable to express his wishes due to his young age or intellectual disability, the village group or other villagers shall apply on his behalf. After democratic evaluation by the villagers committee, if the conditions stipulated in Article 6 of these Regulations are met, an announcement will be made within the village; if there are no major objections, the villagers committee will submit the evaluation opinions and relevant materials to the township, ethnic township, and town people's governments for review. The township, ethnic township, and town people's governments shall submit review opinions within 20 days from the date of receipt of the review opinions, and submit the review opinions and relevant materials to the civil affairs department of the county-level people's government for review and approval. The civil affairs department of the people's government at the county level shall make an approval decision within 20 days from the date of receipt of the review opinions and relevant materials.

3. I think the law only stipulates that people without legal support obligations can enjoy it. It does not mention that people with de facto support obligations cannot apply. I think you can apply. Please consult the local civil affairs department for details. In addition, there is a difference between legal adoption and de facto adoption. From the date of establishment of the adoption relationship, I think it refers to the legal adoption relationship. The household registration has been changed, which has legal effect. De facto adoption does not have such effect.
