[2] In the early 1860s Utina became one of the first female auditors at the Saint Petersburg Imperial University, studying law like her sister and brother.

When Utin received news that he was under close scrutiny of the tsarist secret police, he fled the country in May 1863 and Natalia Korsini followed him.

In her written work Natalia Utina tried to combine the storytelling of love affairs with more contemporary "life issues", which is reflected in her novel Two Worlds (published in 1874 and 1875 under the pseudonym N. Aleyeva).

[11] In her story "Soul Storms" (1889) the heroine is disappointed with marriage, free love, and becomes a witness to the events of the revolution of 1871 in Paris, experienced by Natalia Utina herself.

In the story “Krantz" (1892), the main character is a young doctor, a Jew, but described as "Christian at heart", who is presented as an example of an ideal man capable of sacrifice.

In 1913, plays on which Natalia Utina worked in the late 1880s were published: The Tsarevna Xenia, The Banker, and Ondine (1898–1899), written in collaboration with Pavel Viskovatov, who was the husband of her older sister.

Answering a letter from M. K. Lemke [ru] inquiring about her husband's archives in 1912, she wrote back from Vyborg gubernia that there had been a fire in her estate, which destroyed the house and everything in it.

Natalia Utina's last known letter, dated June 16, 1913, is to Lemke, telling him about her intention to remain in Finland until the end of her days.
