First comes love, then comes a royal marriage? What to know about Prince Harry and Meghan Markle's next steps

Harry and Markle sparked engagement rumors with a recent joint appearance.

The first six people in the line of succession to the British throne are required to ask the monarch for permission to marry under the Succession to the Crown Act.

Harry is currently fifth in line to the throne.

Vacation in Africa

Harry has described Africa as his "second home."

"This is where I feel more like myself than anywhere else in the world," he said earlier this year. "I have this intense sense of complete relaxation and normality here."

William and Kate lived together for several years before announcing their engagement.

Markle is expected to relocate to London after wrapping her shooting schedule for "Suits." She is expected to move into Harry's Nottingham Cottage at Kensington Palace.

Engagement announcement

If Markle and Harry do get engaged, Kensington Palace will make a formal announcement, which will be followed by a public appearance of the couple.

Harry and William's parents, Charles and then-Lady Diana Spencer, also made a formal announcement of their engagement in 1981 and later spoke to the press.

Royal engagements typically last no longer than five to six months.

William and Kate’s third child is due next April, leading royal watchers to believe that if Harry and Markle wed, it would take place after April 2018.

Markle's divorce not an impediment

Markle's status as a divorcée -- she was married to Trevor Engelson from 2011 to 2013 -- would not be an impediment to marrying Harry.

Charles married Camilla, a divorcée, in 2005.

Wedding location

Where Harry's and Markle's hypothetical wedding ceremony would take place appears to still be an open question.

William and Kate were married at Westminster Abbey in 2011.

Queen Elizabeth might prefer that Harry and Markle follow in Charles's and Camilla's path and have a civil ceremony at Windsor Castle followed by a less formal blessing and service in the castle's chapel, St. George’s Chapel.

Engagement ring

William proposed to Kate with the 12-carat sapphire and 14-diamond ring Diana received from Charles.

Harry could select a piece of jewelry from his mother's collection -- which he and William inherited after her 1997 death -- or he could opt for an entirely new design.

Royal title

If they do get married, whether Harry and Markle receive a title is at the discretion of Queen Elizabeth.

Harry and Markle could potentially take the title of the Duke and Duchess of Sussex or the Duke and Duchess of Buckingham upon marriage.
